BOILER-LE VE LE R Specification of Letters l atent.

Patented Sept. 24,1907.

Application filed August 11, 1906. Serial No. 330,184.

To all whom it may concern.-

Be it known that I, EARL J. BUDD, a citizen of the United States,residing at Kettle Falls, in the county of Stevens State of Washington,have invented certain new and useful Improvements in Boiler-Levelers;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention has reference to leveling attachments for boilers itsobject consisting in the provision of means whereby the boiler of atraction engine or similar machine may be at all times maintained in ahorizontal position during the travel of the engine on uneven ground orup and down hills.

A further object includes the provision of means for guiding the frontend of the boiler in itsupward or downward movement.

To thisend the invention resides in the attachment to the front axle ofthe engine of a U-shaped guide the arms of which pass through earsprovided on opposite sides of the boiler, the guide carrying a threadedrotatable rod having play within the threaded opening of a block securedwithin the interior of the boiler, whereby rotation of the rod in onedirection or the other will effect a corresponding upward and downwardmovement of the front end of the boiler.

The invention further consists in the construction,

combination and arrangement of parts all as hereinafter fully described,specifically claimed, and illustratedin the accompanying drawings inwhich, Figure 1 is a side elevation of a traction engine provided withthe improved leveling attachment. Fig. 2 is a transverse verticalsection through the front end of the boiler taken approximately on line22 of Fig. 1. Fig. 3 is a top plan view. Fig. 4 is a perspective view,of the U-shaped guide.

Like parts are designated by corresponding reference numerals in theseveral views.

Referring more particularly to the drawings 5 and 6 designaterespectively the front axle and wheels and 7 and 8 the rear axle andwheels upon which the boiler is carried.

The front axle is provided with a vertically disposed U-shaped guideframe 9 mounted thereon, in which is journaled -a threaded shaft 10. Thehorizontal or bottom portion of said guide is connected by means of apair of braces 12 with cars 13 provided on opposite sides of the firebox 14 of the boiler, the rear axle 8 being connected with the rear endsof braces 12 by means of brace rods 15.

Journaled in one of the arms of the guide is a shaft 16 provided at itsinner end with a beveled pinion 17 in mesh with gear 11 keyed to thethreaded shaft 10,

the opposite end of shaft 16 havingsecured thereto a pinion 18 driven bya pinion 19 carried on the front end of an inclined shaft 20 journaledin brackets 21 formed on the corresponding side of the boiler, and

having a hand wheel 22 secured to its rear end.

Located in the interior of the boiler at the front end thereof is astationary metal block 23 having a threaded opening 24 formedtherethrough to receive the threaded shaft .10. Said block and shaft areinclosed by a tubular casing 25 mounted in the interior of the boilerand provided with a lining 27 of asbestos or other heat insulatingmaterial to prevent undue heating of the threaded shaft.

The front end of the boiler carries a pair of perforated ears 26arranged on opposite sides thereof through which the arms of theU-shaped guide extend.

It will be understood from the foregoing that when the inclined shaft 20is turned in one direction or the other by its hand wheel 22 thethreaded shaft 10 will have a corresponding rotation thus effecting theraising or lowering of the front end of the boiler, the perforated ears26 guiding the boiler during such move- 'ment and further preventing anylateral movement thereof.

The connection between the front axle and the U.

shaped guide is such that-the former may be swung in either direction toallow the engine to be steered, the inclined shaft 20 extendingrearwardly to a point within reach of the driver of the engine.

Various modifications and changes may obviously be .made within thescope of the appended claims without departing from the spirit of theinvention.

What is claimed is The combination, in a machine of the class described,including front and rear axles; of a boiler provided at its front endwith a pair of perforated ears formed on opposite sides thereof; avertically disposed II-shaped guide mounted on the front axle, the armsof said guide extend ing through said ears; :1 rotatably mountedthreaded member carried by saidg'uide and extending into said boiler; atubular casing arranged Within the boiler and adapted to receive saidthreaded member; a stationary block mounted in the interior of saidboiler within said casing and provided with a threaded opening throughwhich said threaded member extends; a gear secured to said threadedmember exterior-1y of the boiler; a shaft journaled in one of the armsof said guide; a gear secured to said shaft in mesh with saidfirst-mentioned gear; and means for rotating said shaft, to effect therotation of said threaded member and the consequent raising or loweringof the front of the boiler with respect to said guide.

In testimony whereof, I affix my signature, in presence of twowitnesses.
